SpaceNASA’s Parker probe spots rogue waves and magnetic islands on the sun
The Parker probe’s first data is giving scientists a look at what’s to come as the craft moves closer to the sun over the next few years.

SpaceDust-shrouded monster is a snapshot from the early universe
Scientists have spotted a massive galaxy from the early universe shrouded in dust. It turned up in a small survey by the ALMA radio telescopes in Chile.

SpaceExplainer: Understanding meteors and meteor showers
Meteors regularly enter Earth’s atmosphere. Most ‘shooting stars’ pose few risks to life on the ground, but the rare big ones can be lethal.

PhysicsMagnetic fields may supercharge the sun’s release of heat
Astronomers have linked flame-like tendrils rising from the sun to changes in its magnetic fields. This may be one step toward understanding why the sun’s corona is so very, very hot.

PlanetsSmall, distant worlds are either big Earths or little Neptunes
The Kepler space telescope data are in. They split Earth-like exoplanets into two groups and reveal 10 new rocky planets in the ‘Goldilocks’ zone.

PlanetsJupiter may be the solar system’s oldest planet
Jupiter’s early existence may explain the odd arrangement of planets in the solar system, a new study suggests.

PhysicsGravitational waves detected yet again
For the third time in 16 months, scientists have announced detection of gravitational waves washing over the spacetime environment in which Earth resides. This seems to show that such waves may not be rare.
